Title: Method for obtaining more economical extraction of the valuable constituents of those minerals which contain iron at lower states of oxidation than fe2o3 in their molecular structures
IPC: C22B1/14
Filed: 1960-06-18
Abstract: Fe is removed from a mineral which contains FeO in its molecular structure by roasting at 700-750 DEG C., to convert the FeO to Fe2O3, reducing at 900-1260 DEG C. and removing the resultant mixture of Fe3O4 and Fe by leaching. The desired constituents in the ore may be left in the residue or may be removed with iron in the leaching step. The reduction may be with CO or H2 or by mixing fine soft coal with oxidised material and roasting. Minerals to which the process may be applied include ilmenite, ferberite, wolframite, ampangabeite, aenigmatite and allanite. The process is exemplified by iron extraction from ilmenite with a sulphuric acid leach. A tungsten or rare earth ore may be similarly treated. Specification 951,086 is referred to.

Title: Controlled self-locking sealing device for the tightly locked junction between two parts or structures and the various applications thereof
IPC: B63B19/26
Filed: 1965-06-24
Abstract: A self-locking sealing device between a hatch cover section 4 and the coaming 2 of a ship's hatch 1 comprises a flexible, resiliently deformable tube 13 attached to the faces 11 and 12 of the angle section 10 attached to the coaming ledge 3. In the deflated state of the flexible tube 13 the hatch cover is free to move on rollers 5 along the coaming ledge. In its hatch covering position, rollers 5 of the hatch cover are supported by platforms 8 flush with the runway in openings 9. Locked fluid tight closure is achieved by dropping platforms 8 and inflating flexible tube 13 through introduction of an hydraulic or pneumatic pressure fluid. In its expanded state tube 13 strongly applies itself against the adjacent surfaces of the coaming and the cover. Similar self-locking fluid tight closure is achieved between adjacent, rolling hatch covers and between cover sections hingedly interconnected and foldable.

Patent ES-334518-A1 (ES)
Title: Method of increasing the rate of heat transfer
IPC: F28F9/24
Filed: 1966-12-14
Abstract: Relates to plate or tubular heat exchangers in which passageways for a fluid to be heated are formed between spaced-apart passageways for the heating fluid defined by walls separating said two fluids from one another. According to the invention, in such a heat exchanger, an ionic discharge is created in the passageways for one or both fluids and is said to effect an increase in the rate of heat transfer by generating a transverse flow component in the fluid. The ions may be discharged from electrodes (38) charged from a suitable source of direct current, the electrodes being mounted on and electrically insulated from the passage walls. The discharge of ions may be periodically terminated to enable the fluid or fluids to scour the passage walls of deposits.

Title: Coating apparatus and method
IPC: D06N3/00
Filed: 1967-10-10
Abstract: Coating apparatus comprises a stationary member having a curved surface provided with a longitudinal cavity creating a fluid-holding pocket on said surface under a web fed thereover, means for introducing coating fluid to said cavity, and means for removing excess coating fluid from said cavity. As shown, a fixed cylindrical tubular member 11 is provided with a fixed internal partition 22, and liquid coating medium, delivered under pressure through an opening 23 to one interior chamber 20 thus formed, passes to the outer surface of member 11 via a line of apertures 13. A line of apertures 14 connects the outer surface of member 11 with the other internal chamber 21. A web 10 passes over apertures 14, 15 and over a wire-wound driven roller 12 journalled at 'the surface of member 11 on the outer side of the apertures 13. Web 10 is biased against the .surfaces of member 11 and roller 12 by a leaf spring 26. The coating medium issuing from apertures 13 forms a pocket 15 of liquid between roller 12, the -outer surface of member 11, and the 'under surface of web 10 travelling towards roller 12. The web thus coated passes over the latter and the excess liquid passes through apertures 14 into chamber 21, to escape therefrom, for re-circulation, through an opening 24. The web initially passes over a roller 29 carried' by an arm 34 axially adjustable for varying the angle of approach of web 10 to member 11, In a modification apertures 13 are replaced by a continuous slot the width of which may be varied by turning a screw connecting the outer wall of chamber 20 diametrically with portion 22. In a further modification, roller 12 is replaced by a fixed ridge.

Patent ES-361680-A1 (ES)
Title: Continuous-casting mold with refractory top liner
IPC: B22D11/07
Filed: 1968-12-20
Abstract: A refractory collar 11 on the top end of an open-ended mould 10 has a flange 12 depending into the mould cavity 13 gas (such as nitrogen) from passages 22 prevents molten metal entering a space 20 between the flange 12 and the mould wall. Preheating of the flange 12 by an embedded graphite electrical conductor 18 inhibits freezing of the melt within the collar so that scum collecting on the melt surface may be drained off periodically through a spout 17 at one end of the collar 11. Oil is introduced to the mould through passages 24. Melt entering the space 20 is detected by thermocouples 23 which cause the gas pressure to be raised to force it out. The refractory collar 11 has an angle-iron frame 14 with slotted lugs 16 which co-operate with bolts 15 pivoted to the mould top to secure or release the collar.
Patent ES-372786-A1 (ES)
Title: Device for manipulating copper bars
IPC: B21B39/22
Filed: 1969-10-22
Abstract: An apparatus for manipulating bars so that each face of the bar may be inspected for faults. The apparatus has a conveyor to feed a bar to an inspection table which houses angle iron members at each inspection station along the table. The angle irons engage a bar, lift it from the table, rotate it to expose its next face to inspection, and deposit it at the next inspection station. A tray is located at the end of the inspection table for unloading an inspected bar. The last angle iron deposits an inspected bar on the tray. The tray lifts the inspected bar and deposits it either on a conveyor for accepted bars, or on another conveyor for rejected bars. The unloading conveyors abut the outlet end of the table. The end segment of one conveyor is mounted to move in upward and downward directions relative to the table. When the inspected bar is to travel along this conveyor, the segment is in its downward position abutting the end of the table, and the tray will deposit the inspected bar on this conveyor. When the inspected bar is to travel along the other conveyor, the segment of the first conveyor is raised upward out of contact with the table to supply clearance for allowing the tray to deposit the inspected bar on the other conveyor.

Title: Process for producing a polymeric material
IPC: C08J9/00
Filed: 1975-02-25
Abstract: The incorporation of additives into thermoplastic polymers, in particular to give foamable polymers, which are used for the preparation of an extrudable melt is carried out without the use of an adhesion promoter by adsorbing the additives onto foam flakes, optionally mixed with polymer granules, and adding them in this form to the thermoplastics before the melting.
